INGV-CT reported that during 25-31 May the NW-SE-trending fissure E of the Etna summit craters continued (since 13 May 2008) to produce active lava flows to the N of the SE end of the fissure, along the W wall of the Valle del Bove. At least three lava flows were active. Elsewhere on the volcano, activity was restricted to degassing from the Northeast Crater, from the NW and SE Bocca Nuova vents, from the E flank of the Southeast Crater, and along summit fumarolic fields. The activity was observed directly and by utilizing surveillance cameras in Milo (about 11 km ESE).
